IMPORTANT
WE RECOMMEND THAT THE FILTER ELEMENT
BE REPLACED BEFORE ENGINE
PERFORMANCE IS AFFECTED. THIS MAY
OCCUR AT 250 HOURS OF SERVICE UNDER
VERY DUSTY CONDITIONS OR AT 500 HOURS
UNDER NORMAL OPERATING CONDITIONS.
WE DO NOT RECOMMEND CLEANING THE
FILTER ELEMENT BECAUSE OF THE
POSSIBILITY OF DAMAGING IT.
CHECKING THE ELEMENT
To check for damage, pin holes, etc. shine a light
source into the end of the element. If light CANNOT
be seen through the paper, a new element should
be installed. Likewise, if pinholes of bright light
appear in the paper, the element should be
replaced.
INSTALLING ELEMENT
1. Clean the dust from inside the filter
housing with a damp cloth. Make sure that
dust does not enter the engine air intake.
2. Check the soft gasket material at both
ends of the element to be sure it is not
damaged.
3. Insert the open end of the element into the
housing and press it onto the air intake
pipe at the back of the housing. Make sure
the filter element fits over the pipe snugly
and is pushed all the way on to prevent
any dust from getting past the filter.
4. Install the air cleaner cover over the
element with the dust collector pointing
DOWN (dust collector empties
automatically when properly installed).
Secure the cover with the two wire bails
(See Fig. 34).
